Your childís security is Diono's top priority. The Radian rXT was engineered with premium, innovative features like a steel alloy frame, aluminum reinforced sidewalls, energy absorbing EPS foam and a reinforced adjustable head support to keep your little one protected and comfortable.

The radianģ rXT keeps children comfortably rear-facing from 5-45 pounds for the safest possible position. Premium, plush head and body support cushions are included for newborns and infants.

Accommodates forward-facing children up to 65 pounds in a 5-point harness and converts to booster mode for kids 50-120 pounds. The aluminum reinforced, adjustable head support and sidewalls provide additional side impact protection.

I have a four year old and twin 1 year olds. I originally bought two rear facing only seats for my twins (had to do some research to find three that would all fit in my car). Now that I moved my twins to forward facing I had to purchase another two seats for them that would fit along with the booster I have for my four year old. These seats are narrow enough to easily fit three across either forward facing OR rear facing. I have one fairy wide booster seat + two Radians and while its a bit tight, it easily works. I've also moved all three to different cars and it fit all of them without issues. If I had three Radians it would be even be easier (since my booster is a few inches wider than these seats). My kids like the seats, seem comfortable to them, and are easy to buckle them in with. I didn't try rear facing with the kids in them, but I put them in the car just to see and space was ok that was too. I currently have 10 car seats including my two Radians, and these are one of the easiest ones to install of the bunch.If you are looking to fit three kids in a standard car (I have a Tucson and an Altima), I would recommend going with these. My only regret is that I didn't purchase these originally instead of buying separate infant carriers.

Prosfits three across in a standard size vehicle (Camry, Fusion, Altima, etc). Rear facing OR front facing.

Great car seat

Love this car seat. Easy to install. My 3 year old is still rear facing and doesn‚€™t complain about comfort. Great when you need narrow seats. Only con is it‚€™s really heavy so wouldn‚€™t recommend if you have to move the seat often.

Favorite Car Seat

I work in car safety research so besides a safe car I am always on the lookout for the safest car seat. This seat has really great reviews from people as well as the industry. We do not have the biggest car so this seat is great if you need to fit three across or if you need to keep two seats side by side so that one more adult can fit in the back. My son looks comfortable in the seat as well. Albee Baby has the best price on this seat and the rewards program is the best. Highly recommend!

Great compact car seat

Our friends had recommended trying these so we could get three car seats across in a small car. These fit perfectly and it‚€™s pretty easy for our almost 3 year old twins to get in and out of. Plus, the product was cheaper here compare to competitors. Would definitely recommend, especially if you are looking for car seats for a more compact car!

Love these seats & so do our girls!

We love the Diono Radian RXT! We purchased due to its slimness and needing 3 seats across. The material is soft and comfy, the seats are super strong and durable feeling and they‚€™re really easy for our girls to climb in and out of. Our girls prefer these over their previous Graco.

They‚€™re incredibly sturdy, safe and within a decent price point as far as car seats are concerned;I love that they‚€™re slim enough that I can fit three across in my suv or in my husband‚€™s smaller car if need be.

Liked it so much, we bought two!

This is a very versatile, very comfortable car seat. Our 4 year old still uses his and we bought another for our 7 month old because he's growing out of his smaller seat. The removable infant cushions are a great fit for him. Straps are comfortable with a very soft padded cover on the harness. The only downside is that it is quite heavy to carry, but we only do that when we travel by air. The heavy steel frame does mean great safety, though. Highly recommend!

Three across, Best for the Money

We drive a Ford Focus which is, in my opinion, only a medium sized car. The choice was between buying a new car or two Dionos when we had our third child because there was NO WAY we were getting a third seat in with our daughters previous booster. Although Dionos may be one of the more expensive car seats out there, they certainly are cheaper than a new car! We still are able to use our original infant carrier with the two dionos but I like these so much I will likely be purchasing a third eventually. They‚€™re solidly made and have the most room to grow I‚€™ve found, especially for rear-facing, and I‚€™ve done a lot of research. I like the side impact head rests as most children are killed or injured in side impacts, and also they make sleeping easier for the child as their head won‚€™t rock forward as easily. Best bang for your buck and cheaper than Amazon even on this site!!

ProsNarrow and large age range, able to rear face for very long. Fits three across, best quality you can buy

ConsHeavy, top heavy/tips over (when free standing), some people with larger hands may have more difficulty with the install

Best UsesFamilies with more than two children (or are planning on more than two eventually) or anyone who cares about buying the best safety for their child due to the high quality and rear-facing abilities.

I never used these for rear-facing, but for forward facing they lasted quite a while even for my tall boys. We kept these in Grandma's car so they were not used daily, but they were easy for my boys to Buckle in and out and I felt they were very safe in these. Plus the colors are great!

Slim Carseat, Just What We Wanted

After much research, we ordered the Diono Radian RXT wanting a safe convertible seat to last and also narrow enough to install next to another carseat. This is it! It's taken a little getting used to, but now a week in of using it, we really like the ease of the harness and my son has never once cried out in discomfort.

Always a great experience shopping at Albee - lowest prices on line and best high end product shopping for kids !

ProsLove the car seat bought on flash sale -

ConsNot the color I wanted and upset that the color I wanted cane on sale the fooowing week but it?s ok anyway

A year later we still use this carseat, we've never had any issues and its in great condition besides a few goldfish crumbs. My daughter loves it and can climb inane out on her own. She rides rear-facing and its the only carseat that fits 3 across rear-facing in my car. Now that her twins brothers are outgrowing their infant carseats we will be purchasing the same seats for them! Diono is great!

I am praying that we can get our other seats to work.

We're trying to fit 3-across in a sedan, and of course, that's a nightmare regardless of what seats you have. We got this one because it's so narrow, and would likely make a 3-across setup easier to achieve. But OH MY GOSH, I hate this thing so bad. It weighs 3 times more than our other car seats, it is way less intuitive to use, and honestly if there's any way whatsoever to get our other Graco seats to work in our Honda Civic, I'm sending this behemoth back immediately.

This thing was probably designed by NASA. Sturdy and compact? Check and check! Could probably keep your kid safe in the Challenger explosion! Short of needing to travel outside earth's atmosphere, I can't see why this seat would be anyone's first choice, because I definitely feel like I need to be an astronaut to make adjustments to this seat.

We were having issues getting all three of our kids in the back safely in their car seats and booster.

All the kiddos are much happier now and I don't have any worries about their safety anymore.

They are easy to install, narrow across the seat, and my daughter is very comfortable in it. I also very much love the safety features and that the frame is made of steal.

Diono FTW!

We got the Diono Radian RXT and love it! We've had Graco, Chicco and Britax for our older kids, and we're really liking the Diono car seat. It is very heavy, so it's not easy to move from one car to another, but that's something we don't encounter on a daily-basis. Overall, I highly recommend this car seat!

Good overall carseat

This seat is easy to install. The one downside is how long the back support is on this car seat. It takes up a lot of space when rear facing. The one upside is that it is a slim profile on the seat so you have more room between seats. Overall this seat is pretty good and my kids love to sit in it.

The seat works well for kids with regular torso-lengths

My youngest is a regular-sized kid for his age and fits into both his 120 and his RXT just fine. My oldest is 6 yrs, 50 lbs, and 50", but his shoulders are already touching the bottom of the wings in the RXT. That seat isn't great for kids with long torsos.

Love this car seat!

We love the diono. It‚€™s not too bulky like some can be and it seems comfortable for our 1 yr old. It is heavier than most but I‚€™ll take that for a steel frame. I deducted one star because of the installation. It‚€™s relativeky easy but you can‚€™t really transfer this car seat to others cars easily. And without the angle adjuster I‚€™m not sure what car it would fit into without the passenger seat pushed all the way up! But it‚€™s east to wash and safe for my boy with a slim design so I‚€™m sold!

This is our second Diono, and (after trying multiple other cheaper car seats) the quality of this brand just can't be beat. This is a solid, steel-framed car seat that ranks HIGHLY in safety. It's the only car seat that can fit 3 in a row! We love Diono!!

Super pleased with the Radian!

We purchased two Radians. In the past, we have used Britax convertible seats; I have much older kids and have had Boulevards and Marathons, and we currently have two Marathons in our other car. We needed something with a higher rear-facing weight for our beast child, and the Radians have been reviewed so well (both professionally and by friends). We were trying to choose between this and the Clek Foonf for back-to-front space and a higher weight limit, and these were smaller. We have not been let down.

They are easy to install. They are narrow. They don‚€™t take up as much room front-to-back (but buy the wedge/positioner if you have a rear facing kiddo). The thing that impressed me the MOST is that these seats feel truly comfortable.

I like the solid, darker colors because they don‚€™t show dirt or stains like many other seats I‚€™ve had. I‚€™m a sucker for bright colors and fun patterns, so this isn‚€™t something I thought I would like, but I do.

No complaints. Be warned, though: This seat is heavy. I cannot emphasize that enough. If you are someone who has to move seats a lot or, more importantly, if you need to have a car seat that you use frequently for air travel, this may not be the right choice for you.

Good quality. Fits in our vehicle 3 across. Arrived in good condition and as anticipated.

Love the safety and comfort these provide

I was replacing car seats for my almost 1 year old and my 3 year old. Though I had the Nextfit convertible, my toddler just didn't like it much b/c she felt squished in it though she was a very slender child. I had planned on getting her into a booster seat at 4 so wasn't really interested in buying a new carseat. But after some research found the Diono Radian RXT. I loved the safety ratings and understood it was very heavy. But both these seats would be going in the captains chairs in the 2nd row of my SUV and I planned on never moving it. But what I really loved is that the sides were relatively low profile and felt roomier to my daughter. She didn't fall into her seat like other convertibles but just sat into it like a regular chair which made my job easier b/c I didn't have to help her dig herself out anymore.I also purchased a wedge seat adapter piece for my youngest daughter's seat so she is able to see outside the window or across to her sister easier.I got the black scarlet which looks nicer and is softer than expected. Easy to clean and relatively easy to install...the lifting it into the car was the hardest part. Just YouTube it and you should see quite a few Diono installation videos.

ProsExcellent safety ratings.
Works for every stage from birth to booster and comes with all the cushions you'll need for each stage.
Easy for toddlers to use.

ConsHeavy...if you're planning on moving the car seat between vehicles, this may not be the ideal carseat.

Great, trustworthy seat

I love the seat so much, I bought another for our 2nd child. I trust Diono the the safety of my family!

I already owned an older model of the RXT (about 3 years older) and love it. So, when I needed another seat for the younger brother, I decided to purchase the RXT again. This time I bought two, one for a Mercedes Benz C350 and one for a Toyota Sienna. The seats were easy to install in both cars. In the C350, with two seats (one in the rear center and one in the rear passenger side), I still have room for someone to sit in the rear driver seat. In the Sienna we also have a Britax car seat. In comparison, the Diono straps are much better. The Britax straps constantly get twisted. This is not a problem with the Diono seats. The Britax also takes up much more space in the car as well.

Solid and safe car seat

We've owned this car seat for a few weeks now, and so far I really like it. The steel frame construction and extended rear facing were the main selling points for me. Installation took some time, but I have peace of mind knowing the car seat is securely attached to my car. I especially like the tether that attaches from the back of the car seat to the front seat track which is bolted to the frame of my car. I purchased the optional angle adjuster which added several inches of space between the car seat and the back of the front seat in my tiny car, and also made the car seat conform better to the backseat of my car, which makes it feel even more stable and secure. When I try to move the car seat side to side with my hand, it barely budges at all. In addition to all the great safety features, the car seat's low profile makes getting my son in and out of the car seat much easier than with other car seats. He also seems to enjoy the freedom of movement he has in this seat compared to others.

Plastic warped after 15 months. Harness constantly binds.

The plastic on rear facing base turned white and warped after 15 months of use. Diono customer service refused to provide a replacement, they only guarantee their seats for 12 months from date of purchase. The 5 point harness gets stuck constantly, especially when the seat is installed rear facing. I have to fight to tighten the harness each time I put my children in these seats. The shoulder strap for travel is useless. The clips for installation in the car should be self ratcheting for this price point. My husband and I have to fight for 30 mins with each seat to get it properly installed (where another brand takes 10 minutes per seat maximum). Never tested this seat in an accident but with it's severe engineering flaws I'm not confident that I will protect my children and the company does not stand behind their product.
